....Thanks again .... Yes, I'm going to go with the split duration cam even though my engine builder says not to. Well, he doesn't say not to, he just says that I'll lose TQ. if I go split. But NO ONE else seems to agree with him! No one on this board, AFR, Comp Cams, Lunaniti or Desk Top Dyno {or the guy who first built my engine}.... So split it is..... Bill
